摘要

本研究針對人工重建造林的5種原生樹種（櫸木、光蠟樹、楓香、烏心石、青剛櫟）進行每木調查等試驗。依不同海拔高度及不同坡度級進行試驗，結果顯示烏心石在海拔400-750 m有較佳徑生長及高生長，對於坡度的反應也最為明顯，隨著坡度的增加，徑生長及高生長接趨於衰退。因而櫸木、光蠟樹及楓香在10-20°的坡度上，有顯著最佳的徑生長與高生長。本研究結果將可提供未來研訂林業政策及後續經營時之重要參考依據。

In this study, five native species (Zelkova serrata, Fraxinus griffithii, Liquidambar formosana, Michelia compressa and Cyclobalanopsis glauca) were investigated, compared and analyzed at different altitudes and different slopes in rehabilitated forests. The results showed that Michelia compressa had better diameter and height growth at 400-750 m, and its growth was obviously affected by slope with growth decreasing as slope increasing. Besides, Zelkova serrata, Fraxinus griffithii and Liquidambar formosana had the best diameter and height growth at 10-20° slope. The results from this study could provide a guideline for formulation of forest policies and management.
